WALL-PAPER FASTER A N D TREMMER.

Application filed. July 21, 1919. Serial No. 312,358.

To all whom t mag/concern:

Be it known that I, HENRY L. MABKLEY, a citizen of the United States, residing at Minneapolis, in the county of Ottawa and State of Kansas, have invented new and useful Improvements in 1Wall Faper Fasters and Trimmers, of which the following is a specification.

The object of the invention is to provide a machine which will apply lpaste to wall paper and trim the selvage edge thereof preparatory to the papers being applied to the wall. To this end the invention comprises a main frame, a supply roll spindle on which the roll of wall paper to be trimmed' and pasted is carried, intermediate rollers over which the wall paper passes from the supply roll to be brought into contact with a paste applying roll rotating or traveling in a suitable paste receptacle.

Attendant on the paste applying rolll there is a scraper element which may be adjusted toward and away from the paper after the latter has passed over the paste roll. By means of this scraper the thickness of the paste applied to the paper is regulated.

A further object of the invention -is to provide a machine of the character described which is simple in construction, durable and effective in operation and inexpensive to manufacture.

@ther and further objects appear in the following description wherein the invention 'is set forth in detail. To the `exact construction in which it `is shown and described, the invention is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible in spirit with the annexed claims.

Fi Figgl l Fig. 6 is a section on the line 6 6 of Fig. 2 i

Fig. 7 is a section on the line 7 7 of Fig. v1 Y Fig. 8 is a section on the line 8 8- of Fig. 2. As shown, the invention comprises a box like frame 1 having the shape preferably of a rectangular parallelepiped but having one side wall cut away, as indicated at 2, the top ofthe frame being left open so that paper carrying rolls supported by a .sup-

plementary frame may engage paper carried in the main frame.l At that side opposite the open side 2, an arcuate plate V3 Lis carried, this plate 3 attaching to the frame at the upper edge adjacent theclosed side and 'attaching toy the closed ends of the frame at a point between Vthe center ofthe latter and the open side. This plate 3 constitutes the bottom of a paste reservoir in which a supply of paste, such as is indicated at 4 may be carried.

A paste supply drum or roll 5 is employed and is rotatably mountedY in the paste reservoir by lmeans of trunnions 6 carried onits ends, one of these trunnions resting in a suitable bearing in one end of the frame l 'and the other being engaged in a bearing 7 which is carried in a sleeve 8 mounted on the opposite end of the frame. A spring 9 Vis inclosed within the sleeve and bears on the bearing element tending to force it 'toward the drum 5 but the bearing element is provided with a stem l0 projecting fromy the sleeve member 8 andformed with a knurled head 11 at its end by means of which it may be moved against the pressure of the spring 9 to release the bearing 7 from its attendant trunnions 6. 'Thus, when it is desired to remove the drum 5 for the purpose of cleaning. the paste reservoir, the bearing 8 and the means by which it is mounted provide for the ready removal of the drum. Y

ArEhe paste applying drum 5 is rotated by the paper which passes over it, the frictional contact of the paper effecting the rotation of the drum which moving in the paste 4L carried in thereservoir carries the latter up for'application to the passing paper.

through the thimble 12. A. spring 16 surrounds the-stem (which is of less diameter than the stud proper) and is pressed between the end of the thimble andthe shoulder formed at the junction of the stud with its stem. This spring, therefore, tends to force the stud in the direction of the opposite side of the frame. The stud 14 at its inner end--V that is7 the end projectingk into the `inside of the frame-carries a disk 17 which is formed with a hub 18 through which there passes a set screw 197 the latter bearing upon the stud and securing the disk thereto.V From its inner end the stud is bored in the direction of its length to receive one end of a spindle 20, the latter being designed for carrying means for a roll to be pasted. On the opposite end of the spindle 2O there is 'Xedly attached a disk 21 which,V together with the disk 17 serves as a flange for the spindle to preclude longitudinal movement of the paper roll along thespindle once ity-is attached thereto. That end of the spindle 2O at which the disk 21 is carried has a pivotal bearing in the bearing member 22 which is similar to the bearing element or member 7. This bearing member 22 is carried in the thimble 13. Its inner end stands within the frame and its stem is inclosed in the thimble, as spring 23 tending normally to draw the bearing member 22 away from the connecting end of the spindle 20. Acting in opposition to the spring, however, there is a screw 24 which is formed with a knurled head 25. This screw threads into the thimble from the outer end thereof and bears against the end of the stem of the bearing member 22. The screw may be employed therefore to shift the spindle 2O in an axial direction and this construction provides for properly positioning the roll of paper relative to the other parts of the machine, s o that` the selvageA edges may be `brought into position for severance at the proper places.

Guard plates 26 are attached to the bottom of the frame adjacent either endV thereof and extend upwardly and partly overhang a roll of paper when the latter is placed upon the spindle 20.

Rotatably mounted in the frame and between the spindle 20 and the adjacent side of the paste reservoir there is a pair of trimming rolls 27 which are carried on a common shaft 28, this latter being rotatably mounted in trunnion bearings 29 mounted in, opposite Vends of the frame7 the bearings 29 being Vsecured to the frame by means of threaded stem portions 30 which project through slots 31these threaded stem portions 30 'receiving the nuts 32 which bear against the outer faces of the ends of the frame and secure the bearings in place. The slots 31 are diagonally disposed and this constructionmakes for the adjustment of the bearings to move the rolls 27 toward or .away from the roll of paper carried on the spindle 20. 'Y Y Thel rolls 27 are loosely mounted upon their attendant shaft 28 'and their opposite ends are held in close proximity to relatively narrow rolls 33 carried by the shaft adjacent its opposite ends but iixedly attached thereto. Spacing washers 34 are interposed between the ends of the rolls 27 and the adjoining faces of the rolls 33 for the. purpose of providing a peripheral slot in which a circular selvage trimming knife may operate. A spring 35 surrounds the `shaft 28 and l is pressed between the adjoining ends of the rolls 27 and tends to keep them in contact with the spacing washers 34. This construction provides for shifting either of the rolls-27 away from its attendant small roll 33 for the purpose of cleaning out the slot provided by the spacing washers between the two should such slot become clogged up as is a ossible condition in practice.

he circular selvage trimming knives opcrate in the slots provided by the employment of the spacing washers 34 and each of these knives comprises a beveled disk 36 securely attached to a roll 37 formed with a hub 38, the latter rotating on a stud 39 projecting laterally from an arm 40 adjacent the one end of the arm. The arm 40 adjacent the other. end has a similar laterally projecting stud of shorter length which enters and is carried in an appropriate eye formed at the upper end of a standard 41 which is attached to the frame. A set screw 42 passes readily through the eye and bears upon the stud 41 to hold the latter securely attached to the standard. Between the disk 36 and the armf40, the stud 39 carriesra spring 43 which surrounds the stud and has one end bearing against the disk. This spring would force the disk, the hub and the wheel off the stud were not a cotter pin 44 provided j and inserted diametrically through the stud adjacent its free end. This pin, therefore, takes the place of the hub 38 while the spring precludes too free a rotary movement of the knife during its trimming operation. The retardation of ro-l tation afforded by this spring 4makes for more effective trimming of the selvage than would-be possible were the knife too freely rotated on its attendant stud. The selvage edge trimmed off is, by this constructioin. more effectively kept from clogging.

The frame 1 adjacent each end is provided with a standard :41 and each standard supports a vcutting disk 36 and its attendant parts as has just been described, each cutting disk operating in the place or slot provided by the spaced washers 34 between the rolls 33 and 27.

A supplementary frame 44 is hingedly attached tol the main frame 1 above the spindle 2Oas indicated at 45. This supplemental frame 44 is an open frame comprising two end rolls 46 and two longitudinally disposed plates 47 and 48 which connect the end rolls together. j

Mounted in the .supplemental frame 44 there is a pressure roll 49 which is carried on an appropriate spindle 50, the latter being rotatablyv mounted in bearings 51 carried by the opposite end rails` 46. These bearings 51are oval shaped in cross section with the longest dimension of the oval disposed substantially vertically, so that the roll 49 may yield toward and away from the rolls 27 into contact with which the roll 49 forces the paper passing from the roll carried on the spindle 20.

Disposed in advance lof the roll 49-that is, between that roll and the paste applying roll 5 there is a roll 52 and two coperating rolls 53. The latter two rolls are mounted on a common shaft 54 while the former roll is mounted on a shaft 55.

The two shafts 55 and 54 are rotatably mounted in the opposite end of the levers 56 which are pivotally mounted, as indicated at 57', on the opposite end rolls 46 of the supplemental frame. The pivot points of the levers are adjacent those ends wherein the shaft 55 is mounted. Shaft 54 being mounted in the ends of the longer arm of the lever the pivot points 21 being disposed to one side of the levers, the tendency of gravity will be to cause those ends of the lever iny posite side bearings of the upper frame to limit the distance to which the ends of these levers may drop. The levers 56 are Z- shaped as shown and the legs in which the shaft 54 is mounted are depending legs; the

axis of the rolls 53 is therefore normallyv lower than the axis of the roller 52 and since the levers 56 are pivotally mounted, any tendency to rest rolls 53 will result in lowering the roll 52.

The roll 52 is designed as a pressing roll for keeping the paper in contact with the paste applying roll- 5 and as the paper is led from the supply roll carried on the spindle to the paste roll 5 it passes between the rolls 49 and 27 then underneath the rolls 53 and then over the roll-or drum 5. Obviously when the paper is tensioned between the point where it leaves the rolls 27, and the point where it contacts with the rolls 5 it will tend to raise the rolls 53 with a resultant depressionof the roll 52,'the latter then contacting with the paper as it passes over the roll or drum`5 and maintaining it in firm contact with the drum 5 throughoutthe length 'of the latter.

On the opposite side of the drum 5 from the rolls 53 and 52,'an idle roll 57 is carried, this roll being mounted on a shaft or -spindle 58 which isjournaled in appropriate bearings carried by the side rails 46 of the supplemental frame..

' The paper in leaving Vthe Apaste applying roll passes under this idle roll 57 and in order that the llayer of paste to be applied to the paper may be regulated, there is provided a double edged scraper 59 ywhich is carried by a shaft 60 rotatably mounted in opposite ends of the main frame 1. This scraper 59 on one of its elements is formed with the coarse scraping edge 61 and on the other of its elements with a fine scraping edge `62. Either of these scraping edges is adapted to be brought into close proximity to the pasted face of the papery as it leaves the drum 5 and passes beneath the idle roll 57. In order that it may be positioned with reference to the passing paper as desired,

the shaft 61 by which it is carriedv isy equipped exterior to the main frame with a toothed disk 63 lyingadjacent one end of the main frame, a pivotally mounted pawl 64 being Vmounted adjacent the disk for engagement with the teeth thereof so as to maintain the scraper Vedge elevated to the proper position for thedesired contact with the passing paper.

Inthe operation of the machine, the usual roll of paper is attached to the spindle 20 after the latter has been removed by forcing the bearing stud 12v back against thepressure of its spring 16. Since that end of the spindle which engages the stud carries no disk, the spindle may be readily inserted through the roll of paper and then attached into-position, the bearing stud moved back as before to permitits attachment. If it is necessary to adjust the roll longitudinally to properly position it so that its selvage edges may be trimmed at the line, the screw 24 is turned either right handedly or left handedly to move the roll` in the direction desired. If the screw be turned in one direction'the spindle 20 isforced longitudinally in the direction of that side of the main frame carrying the thimble 12, this movement of the spindle. being against the pressure of the spring 16. If the screw be turned in the opposite direction, the'spring 23 in the thimble 13 operates to draw the bearing ele-` ment within the thimble and the spring 16 serves to force the spindle 20 in the direction of the bearing member or element 22. Thus the spindle 2O may vbeadjusted in either direction to properly' position the roll for the cutting of its selvage edges.

laoY

The roll having been placed on-the spindle as aforesaid the set screws 42 are loosened when the arms may be swung upwardly to lift the trimmingV or cuttingV knives out of their position within the Space between the rolls 27 and 33,k the supplemen- V tal frame being of course raised on its hinged connections to permit access to these set screws. The paper is then drawn off'the supply roll and over the rolls 27, the knives being restored to their normal. positions,

when they Awill sever the paper at the selvage edges. The paper is then drawn over the drum 5 after which the supplemental top is swung down to its normal position `frame to this position, the roll 49 Vbears against the paper forcing it into contact with the rolls 27, the rolls 53 at the same timeY contacting with the paper and being raised as a result of such contact, whereupon the roll 52 is swung down in the direction of the drum and presses upon the paper forcing it into contact with the drum 5, that end of the paper projecting from the machine passing under the idle roll 52. As the paper is drawn off the supply roll by pulling on this projecting end, drum 5 is rotated and because of its immersion in the paste 4, the latter is raised and brought into contact with the paper and the layer of paste thus applied is regulated as desired by the proper `adjustment of the scraper 60 by means of its toothed disk and pawl. The position of the scraping edge of the scraper whether it be the edge Gl or 62 determines the quantity of paste left on the paper and at the same time crushes or knocks off any clogs of paste that might be applied during the operation of the machine.
